PPT-Differential stain

Biology and Biotechnology department Differential stain separate bacteria into group Gram Stain Differentiate bacteria into 2 groups Gram positive bacteria Gram negative bacteria . Objective: to understand how blood stains can give forensic scientists information about a crime.. blood. Blood is what moves oxygen around our body from the lungs to the organs that need oxygen and then back the lungs for more oxygen..

To differentiate the species of bacteria by using differential . stain.. 3- . To study the internal components of the bacterial . Differentiate bacteria into two large groups (the Gram Positive and the Gram negative).. Gram status is important in medicine; the presence or absence of a cell wall will change the bacterium's susceptibility to some antibiotics.
